4Cr13 stainless steel, frequently designated as 40Cr13 or SM4Cr13 in Chinese standards, is categorized as a martensitic stainless steel. The “4” in its nomenclature typically signifies a carbon content of approximately 0.4%.<\/p>\n\n\n\n

4Cr13 steel is a martensitic stainless steel with good machinability. It possesses high strength and wear resistance, as well as excellent corrosion resistance, capable of withstanding steam, weak organic acids, dilute sulfuric acid, and carbonates. Its good polishing performance makes it suitable for manufacturing transparent and opaque plastic product molds that are subjected to high loads, high wear, and corrosive media. Applications include molds for optical lenses (corrosive), resin material products, and resin products with additives. This steel is recommended for all plastic mold manufacturing. Due to its special properties, it is particularly suitable for demanding environments, such as corrosion-resistant and rust-proof molds (e.g., molds for injection materials containing corrosive acetate salts), molds with low surface roughness requirements, complex molds with good toughness and ductility, and large plastic molds requiring high transparency.<\/p>\n\n\n\n
